Cisco ASA DHCP Reservation (Solved)
KB ID 0001751 Problem We have been asking for this for years! Even on my home network I’ve not been able to allocate an ASA DHCP reservation for my laptop and my MyCloud drive.

KB ID 0001721 Problem A while ago I did a run through on site to site VPNs from Cisco ASA to Fortigate firewalls. Back then I said that the default settings were a bit ‘shoddy’ and that I’d revisit it once I had more time. What do you mean shoddy?
